The invention relates to the technical field of road traffic ancillary facilities, in particular to a road surface guiding system of a plane inclined cross intersection. The road surface guiding system comprises pre-warning sign boards arranged at entrance lanes of the inclined cross intersection, isolation piles arranged at both sides of the entrance lanes of the inclined cross intersection, mainrod central left-turn special turn areas arranged near the intersection, Berisha lamp balls arranged at corners of the intersection, channelized island color road edges arranged at the corners of theintersection, left-turn guiding lines arranged in the intersection, warning sign boards arranged at the entrance lanes of the inclined cross intersection near the corners of the intersection, and intersection right-turn visual transition sections arranged at the corners of the intersection. According to the road surface guiding system, the guiding system is arranged at the plane inclined cross intersection, the visual perception of drivers is effectively stimulated, the visibility of the drivers at the intersection is enhanced, and the drivers are provided with sufficient road information tohelp the drivers to pass through the inclined cross intersection safely and quickly.
